Patent FR-2284266-A1 (FR)
Title: Plough beam trip mechanism - has beam tip resting on roller forming upper end of pivoted locking bar
IPC: A01B61/04
Filed: 1974-09-10
Abstract: On the tip beam plough, each beam is contained in a slide and pivots about a pin which slides backwards and forwards in two lateral apertures. Its front end rests on a locking bar, two tension springs maintaining it in the normally forward position. The locking bar pivots on a pin, its position being regulated by a stop bolt and spring. The upper part of the locking bar comprises a roller on which the end of a tip on the beam rests. The weight of the rear part of the beam causes re-engagement after the obstacle has been passed.

Title: Battery using lithium and carbon disulphide - eliminating autodischarge normally occuring with lithium sulphur cells
Inventor: TOUZAIN PHILIPPE
IPC: H01M6/16
Filed: 1974-09-20
Abstract: Electrochemical battery, the novelty being that it consists of a lithium anode and a conducting cathode, connected via an organic electrolyte contg. carbon disulphide at least partially in soln. The battery pref. also contains free sulphur in the vicinity of the cathode or mixed with the latter, the cathode consisting at least partly of carbon. The ratio, free S:CS2, esp. when the sulphur is mixed with the carbon in the cathode, is pref. 0.5-1.5, esp. 1. The electrolyte is pref. an organic solvent contg. e.g. lithium perchlorate, esp. dimethylsulphoxide; propylene carbonate; the dimethyl ether of ethylene glycol; or other solvents listed in the claims. The electrolyte is pref. satd. with lithium trithiocarbonate. Conventional Li-S batteries are subject to self-discharge, which has restricted their use in the past. The invention eliminates this problem and also eliminates the need to use SO2 in cells of this type.

Title: Carburettor with fuel economising valve - has extra air supplied in proportion to engine speed during deceleration
IPC: F02M23/03
Filed: 1974-12-18
Abstract: The carburettor (9) is provided with a slide (11) which covers a hole (12) in the duct (10) connecting the carburettor to the inlet manifold. The slide (11) is connected by the rod (6), bell crank lever (4), and rod (3) to the spindle of the butterfly valve (1). When the accelerator pedal is depressed, the slide (11) covers the hole (12). When the pressure on the accelerator is removed the slide (11) uncovers the whole (12) so that air is admitted to the manifold in proportion to the depression in the duct (10) which in turn is in proportion to the engine speed. Thus at slow running conditions the air supply is virtually unaffected yet pollution is reduced at the high speed during initial deceleration.

Title: Sequential logic regulator circuit - controls process according to largest or smallest of several physical measurements
IPC: G05D23/24
Filed: 1975-07-15
Abstract: The sequential logic regulator circuit is able to adjust an installation by recognising the smallest or largest of several measured values and can compare with a given reference value. For example, a temperature probe (1) is connected into a Wheatstone bridge (2). Its amplified output (3) goes to a voltage controlled oscillator (5), whose output is counted (6) for a preset number of cycles, when it produces an output signal (7). A reference value (c) applied to an identical circuit (9, 10, 12, 13) produces an output (14) corresponding to the reference temperature. The counter outputs pass to AND gates (15, 17) for comparison and operate a control unit (52) via triacs (19a, 20a).

Title: Waterproofing of cardboard by polyester coatings - to obtain a water barrier resistant to delamination
IPC: D21H19/28
Filed: 1976-02-12
Abstract: Cardboard is waterproofed by applying a surface coating of polyester resin to be cured in situ. The process is esp. for treating single or double walled corrugated cardboard for making packaging or for non-stick trays or drawers for holding photographs or documents, where resistance to excessive absorption or loss of moisture is required. The polyester coating is lighter than Al foil, more heat resistant than wax coatings, and less prone than either to delamination. The coating increases the strength of the structure. Porous card structures may be partially sealed with e.g. a cellulose- or starch-based size before the polyester resin is applied. The coating may be applied to one or both faces of the card by spray, brush, roller from solution or suspension as appropriate, may be heat or catalytically cured.
